ERROR: Cannot install -r requirements.txt (line 16) and urllib3==1.26 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested urllib3==1.26
    requests 2.23.0 depends on urllib3!=1.25.0, !=1.25.1, <1.26 and >=1.21.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

PS C:\Users\lalit\Downloads\The-Movie-Cinema-master>

The command to install the packages: pip install -r requirements.txt

After then I ran into the error. How to solve these issues step by step?

make sure use latest versions :

for me fix was using below latest versions

requests==2.28.1 (https://pypi.org/project/requests/)
urllib3==1.26.12 (https://pypi.org/project/urllib3/)

Do what the error message is saying.

To fix this you could try to:

  1. loosen the range of package versions you've specified
  2. remove package versions to allow pip attempt to solve the dependency conflict

Change the requirements to loosen the package versions or just remove the version for urllib and let pip figure it out.

Yeah, I did that too I changed the version and removed it but still the issue not getting solved, still throwing the same error. WARNING: Failed to write executable - trying to use .deleteme logic ERROR: Could not install packages due to an OSError: [WinError 2] The system cannot find the file specified: 'c:\\python39\\Scripts\\jsonschema.exe' -> – Trackman
That's actually a different error, I found a Github issue here. Based on what I read, try running it in administrator mode, see if that works. – Cheerly
